FIG. 1 and FIG. 4 illustrate structures of the middle frame 14 according to some embodiments. As shown in FIG. 1, the middle frame 14 may include a first side frame 140, a second side frame 142 opposite to the first side frame 140, a third side frame 144, and a fourth side frame 146 opposite to the third side frame 144. Each of the third side frame 144 and the fourth side frame 146 may be connected to the first side frame 140 and the second side frame 142, respectively.

In some embodiments, each of the four side frames may substantially be perpendicular the rear cover 12. The four side frames may be fixed to corresponding edges of the rear cover 12. In some embodiments, the four side frames cooperatively form a rectangular frame, such that a cross section of the middle frame 14 may substantially be rectangular. In some other embodiments, the cross section of the middle frame 14 may be circular or stadium-shaped.

In some embodiments, as shown in FIG. 1 and FIG. 4, the middle frame 14 may further include a first side board 141, a second side board 143 disposed oppositely to the first side board 141, and a partition board 145 connected between the first side board 141 and the second side board 143. The first side board 141 and the second side board 143 may be both connected to the third side frame 144. The first side board 141 may be connected to a side of the third side frame 144 close to the display screen 16, and the second side board 143 may be connected to a side of the third side frame 144 close to the rear cover 12. The second side board 143 may define two sliding grooves 100 and 101, and each of the two sliding grooves may be in shape of an arc. A center of an arc in which the sliding groove 100 is located may be coincident with a center of an arc in which the sliding groove 101 is located. In other embodiments, the second side board 143 may define only one sliding groove or a plurality (for examples, three or more) of sliding grooves.

In some other embodiments, as shown in FIG. 5, the opening 14 b may extend through the third side frame 144 along the length direction X and the thickness direction Z, but may not extend through the third side frame 144 along the width direction Y. In this way, the third side frame 144 may be divided into two sub-frames 144 a.

In still some other embodiments, the opening may be defined at an end of the third side frame 144, such that the third frame 144 may be disconnected with a side frame adjacent to the third side frame 144 via the opening. For example, in FIG. 6, an opening 14 c may extend through a part of the third side frame 144 along the width direction Y of the mobile terminal, such that the third side frame 144 may be disconnected with the adjacent first side frame 140.

In some other embodiments, the opening may be defined in two adjacent side frames. For example, according to an embodiment shown in FIG. 7, an opening 14 d may be defined in the first side frame 140 and the third side frame 144.

To be specific, in some implementations, a length of the first side frame 140 and a length of the third side frame 144 may both be less than that of each of respective side edges of the display screen 16 the rear cover 12 (that is, the length of the first side frame 140 may be less than a length of a side edge of the display screen 16 connected to the first side frame 140 and a length of a side edge of the rear cover 12 connected to the first side frame 140; and the length of the third side frame 144 may be less than a length of another side edge of the display screen 16 connected to the third frame 144 and a length of another side edge of the rear cover 12 connected to the third frame 144). In this way, the first side frame 140 and the third side frame 144 may be disconnected from each other at an intersection therebetween. In addition, a length of the second side frame 142 and a length of the fourth side frame 146 may both be substantially equal to that of each of respective side edges of the display screen 16 and the rear cover 12 (that is, the length of the second side frame 142 may be substantially equal to a length of a side edge of the display screen 16 connected to the second side frame 142 and a length of a side edge of the rear cover 12 connected to the second side frame 142; and the length of the fourth side frame 146 may be substantially equal to a length of another side edge of the display screen 16 connected to the fourth frame 146 and a length of another side edge of the rear cover 12 connected to the fourth frame 146). Therefore, the first side frame 140, the third side frame 144, the display screen 16, and the rear cover 12 may cooperatively define the opening 14 d.

In some embodiments, the opening may be defined in three side frames which are successively connected with each other. To be specific, as shown in FIG. 8, in some embodiments, the middle frame 14 may include the first side frame 140, the second side frame 142 disposed oppositely to the first side frame 140, and the third side frame 144 connected to both the first side frame 140 and the second side frame 142. A length of the first side frame 140 and a length of the second side frame 142 may both be less than that of respective side edges of the display screen 16 and the rear cover 12 (that is, the length of the first side frame 140 may be less than a length of a side edge of the display screen 16 connected to the first side frame 140 and a length of a side edge of the rear cover 12 connected to the first side frame 140; and the length of the second side frame 142 may be less than a length of another side edge of the display screen 16 connected to the second frame 142 and a length of another side edge of the rear cover 12 connected to the second frame 142). In addition, a length of the third side frame 144 may be substantially equal to that of respective side edges of the display screen 16 and the rear cover 12 (that is, the length of the third side frame 144 may be substantially equal to a length of a side edge of the display screen 16 connected to the third side frame 144 and a length of a side edge of the rear cover 12 connected to the third side frame 144). In this way, an opening 14 e may be defined by an end face of the first side frame 140 that is not connected to the third side frame 144 and an end face of the second side frame 142 that is not connected to the third side frame 144.

In the above embodiments, the functional assembly 20 may have an outer edge. When the functional assembly is entirely received in the receiving cavity 50, the outer edge of the functional assembly 20 may fit with an outline of the display screen 16 and the rear cover 12, such that the functional assembly 20 may completely close the opening to form an enclosed external frame of the mobile terminal, and prevent dirt from entering the receiving cavity, such that elements in the receiving cavity 50 may be protected.

In some other embodiments, each of two opposite side frames may define an opening. For example, according to an embodiment shown in FIG. 9, each of the first side frame 140 and the second side frame 142 may define an opening 14 f. The opening 14 f may extend through the first side frame 140 and the second side frame 142 along the width direction Y of the mobile terminal, but may not extend through the first side frame 140 and the second side frame 142 along the length direction X of the mobile terminal.

In some embodiments, a rotatable cover (not shown in the figure) may be provided at the opening 14 f. The rotatable cover may be rotatably connected to the rear cover 12 or the middle frame 14. When the functional assembly is entirely received in the receiving cavity 50, the rotatable cover may cover the opening 14 f. When the functional assembly 20 rotates to the outside of the receiving cavity, the rotatable cover may be pushed away by the functional assembly 20.

In some other embodiments, the opening may be defined on the rear cover 12. As shown in FIG. 10 and FIG. 11, in some embodiments, the rear cover 12 may include a first sub-cover 122 and a second sub-cover 124. The first sub-cover 122 may be fixed with the functional assembly 20, and the middle frame 14 may be connected between the display screen 16 and the second sub-cover 124, such that the middle frame 14, the display screen 16, and the second sub-cover 124 may cooperatively define an opening 14 g. When the functional assembly 20 is entirely received in the receiving cavity 50, the first sub-cover 122 may cover the opening 14 g and smoothly transitioned from and spliced with the second sub-cover 124 to form a complete outer structure of the mobile terminal. In some embodiments, the second sub-cover 124 may have a step structure, a step (not shown in the figure) may be formed at a side of the sub-cover 124 that is close to the first sub-cover 122. When the functional assembly 20 is entirely received in the receiving cavity 50, the first sub-cover 122 together with the functional assembly 20 may be arranged to cover on the step to prevent the functional assembly 20 from being exposed to the outside while not in use.

In addition, the middle frame 14 may define other structures, such as a groove, a hole, and the like. The other structures may be configured to arrange elements for specific functions. It is also possible that exterior elements to achieve specific elements may be connected to the mobile terminal in a detachable manner through the other structures. It is also possible that the other structures may be used as a channel through which audio signals or the like may be input or output. For example, the structure may include a groove configured to arrange a power button, a groove configured to arrange a volume control key, or a sound transmission hole, an earphone jack, a socket for a data line/power line, and the like.

As shown in FIG. 2 and FIG. 3, the display screen 16 may be electrically connected to the functional assembly 20, a processor 40, and the like, and configured to display information. In some embodiments, the display screen 16 may be rectangular, and may have four side faces 160 connected to each other end-to-end. The display screen 16 may define a display region 162 and a non-display region 164. When the functional assembly 20 is received in the receiving cavity 50, at least a part of the functional assembly 20 may be covered by the display region 162.

In some embodiments, the display screen 16 may include pixels generated by a light emitting diode (LED) or an organic light emitting diode (OLED), a liquid crystal display (LCD) assembly, or other appropriate pixel structure. A surface of the display screen 16 may be covered by a plate made of transparent glass or layers of plastics. In addition, the display screen 16 may further include a touch electrode, such that the display screen may be used as a touch screen for inputting information, and a user may input signals by a touch operation or perform operations to the information shown on the display screen 16.

The functional assembly 20 may be configured to achieve at least one function distinctive to a display function of the display screen 16. The functional assembly 20 may rotate with respect to the body 10 when the functional assembly is driven by the driving mechanism 30. A rotational axis 20 a of the functional assembly 20 may extend along a thickness direction of the electronic device. That is, the rear cover 12 and the display screen 16 may both be substantially parallel with a rotational plane of the functional assembly 20.

The rotatable configuration of the functional assembly 20 allows the functional assembly 20 to reach various positions on the rotational plane. To be specific, in some embodiments, the functional assembly 20 may rotate between a first position and a second position. When the functional assembly 20 needs to be used, the functional assembly 20 may rotate to a position outside the receiving cavity to achieve a function of the functional assembly 20. When the functional assembly 20 is not needed, the functional assembly 20 may be received in the receiving cavity 50 and covered by the display screen 16. Therefore, the functional assembly 20 may no longer occupy extra space of the display screen 16, and the display screen 16 may be arranged at the front face and occupy the area of the front face as large as possible. In this way, the mobile terminal may have a greater screen occupation ratio.

When the functional assembly 20 is at the first position, the functional assembly 20 may be entirely received in the receiving cavity 50. At this time, a projection of the functional assembly 20 on the display screen 16 may be entirely within the display screen 16, and the functional assembly 20 may not achieve any function due to being covered by the display screen 16, as shown in FIG. 2.

When the functional assembly 20 is at the second position, a part of the functional assembly 20 may protrude out of the receiving cavity 50. At this time, only a part of the projection of the functional assembly 20 on the display screen 16 may be within the display screen 16, and the other part of the projection of the functional assembly 20 on the display screen 16 may be located out of the display screen 16. That is, a part of the functional assembly 20 may not be covered by the display screen 16, such that the functions of the functional assembly 20 may be achieved normally, as shown in FIG. 3.

In other embodiments, the functional assembly 20 may rotate between the first position, the second position, and the third position. When the functional assembly 20 is at the third position, a part of the functional assembly 20 may protrude out of the receiving cavity 50. The third position may be different from the second position.

It should be understood that the first, the second, and the third positions as described above may be examples to illustrate that the functional assembly may be located at different positions. However, practically, the functional assembly 20 may be located at other positions. Regardless of which position the functional assembly 20 is located at, the display function of the display screen 16 may not be impacted. The functional assembly 20 may not occupy any area of the display screen 16, such that a display area of the display screen 16 may be increased, and a display occupation ratio may be increased.

To be specific, as shown in FIG. 12 and FIG. 13 accompanying with FIG. 1, the functional assembly 20 may include a swinging member 22 rotatably connected to the middle frame 14 and a functional component 24 arranged on the swinging member 22. Rotation of the swinging member 22 may drive the functional component 24 to move with respect to the body 10, such that a position of the functional component 24 with respect to the body 10 may be changed, and the functional component 24 on the swinging member 22 may be exposed to the outside of the body 10. When the functional assembly 20 rotates between the first, the second, and the third positions, the functional component 24, which is exposed to the outside of the body 10 when the swinging member 22 reaches the second position, may be the same as or different from, the functional component 24 which is exposed to the outside of the body 10 when the swinging member 22 reaches the third position.

The swinging member 22 may be substantially stripped. In other embodiments, the swinging member 22 may be in other shapes. The swinging member 22 may be made of plastics, metals, or other materials. The swinging member 22 may include a first end portion 220, a second end portion 222 opposite to the first end portion 220, and a connection portion 224 connected between the first end portion 220 and the second end portion 222.

To be specific, in some embodiments, the swinging member 22 may rotate between the first position and the second position, and may be rotatably connected to the middle frame 14 through a rotation shaft 70 fixed on the middle frame 14. On this occasion, the rotational axis 20 a of the swinging member 22 may be an axle center of the rotation shaft 70. The centers of the arc in which the sliding grooves 100 and 101 defined on the middle frame 14 are located may lie on the axle center of the rotation shaft 70. In addition, two sliding blocks 200 and 201 may be arranged on the swinging member 22. The sliding block 200 may correspond to the sliding groove 100, and the sliding block 201 may correspond to the sliding groove 101. The sliding block 200 may be arranged in the sliding groove 100 and slidable along the sliding groove 100. The sliding block 201 may be arranged in the sliding groove 101 and slidable along the sliding groove 101. The sliding grooves 100 and 101, and the sliding blocks 200 and 201 may compose a sliding mechanism of the electronic device, such that the swinging member 22 my rotate along the sliding mechanism smoothly. In addition, a guide block 228 may be further arranged on the swinging member 22, and the guide block 228 may cooperate with the driving mechanism 30.

A plurality of functional components 24 may be arranged on the swinging member 22. The plurality of functional components 24 may be connected to the main board 80 through a flexible printed circuit board 26. In some embodiments, the functional components 24 may include a camera module 240 and a front flash 242. The front flash 242 may be supplementary to a photographic function of the camera module 240. The camera module 240 may have photographing and video-recording functions to provide the electronic device with a video call function, photographic function, and the like. The functional components 24 may further include a rear flash 244 and a receiver 246. The rear flash 244 and the receiver 246 may have functions independent from the photographic function of the camera module 240. It may be understood that, in other embodiments, the functional components 24 may further include a microphone, a loudspeaker, a light sensor, and the like.

As shown in FIG. 14, the camera module 240, the front flash 242, and the receiver 246 may all be arranged on a side of the swinging member 22 close to the display screen 16, and on a same side of the rotational axis 20 a of the swinging member 22. In some embodiments, the front flash 242 may be arranged closer to the camera module 240 than the receiver 246 and the rotational axis 20 a. That is the front flash 242 may be arranged adjacent to the camera module 240 (as shown in FIG. 12). The rear flash 244 may be arranged on a side of the swinging member 22 away from the display screen 16 and symmetric with the front flash 242 (as shown in FIG. 13). The rear flash 244 and the front flash 242 may be connected to the same flexible printed circuit board 26. It may be understood that, in some other embodiments, as shown in FIG. 15, in other embodiments, the camera module 240 and the front flash 242 may be arranged on the same side of the rotational axis 20 a, and the receiver 246 may be arranged on an opposite side of the rotational axis 20 a. Therefore, when he swinging member 22 is at the second and the third positions, different functional components may be exposed to the outside of the body 10.

To be specific, in some embodiments, as shown in FIGS. 16-17, the camera module 240 may be cubic, and an optical axis of the camera module 240 may be substantially perpendicular to the rotational plane of the swinging member 22. The camera module 240 may include a bottom face 241 and four side faces 243. The bottom face 241 may be rectangular and fixed on the swinging member 22. The four side faces 243 may be respectively connected to four edges of the bottom face 241 and substantially perpendicular to the bottom face 241. When the functional assembly 20 is located inside the receiving cavity 50, each of the side faces 243 of the camera module 240 may be tilted with respect to each side face of the display screen 16. For example, in some embodiments, an angle between a side face at a bottom of the camera module 240 and a side face at a top of the display screen 16 may be approximately 10°, as shown in FIG. 16. When the functional assembly 20 rotates in the first direction to the outside of the receiving cavity 50, the swinging member 22 may rotate by approximately 10°, such that the camera module 240 may be arranged at the outside of the receiving cavity 50, and two oppositely disposed side faces 243 of the camera module 240 may be parallel to the side face 160 at the top of the display screen 16, as shown in FIG. 17. When the camera module 240 needs to be used and the functional assembly 20 needs to rotate to the outside of the receiving cavity 50, the rotational angle of the functional assembly 20 may be determined by the tilted angle of the camera module 240 with respect to the display screen 16. In this way, after the rotation, at least one side face of the camera module 240 may be parallel to the side face 160 at the top of the display screen 16.

In some embodiments, the rotational angle of the functional assembly 20 in a direction may be less than 180°, less than 90°, less than 45°, or less than 25°. For example, the rotational angle of the functional assembly 20 may be 10°, 15°, or 20°.

As shown in FIG. 18, the flexible printed circuit board 26 connecting the functional component 24 with the main board may include a first fixing portion 260 fixed on the swinging member 22, a second fixing portion 262 fixed on the main board 80, and a movable portion 264 connected between the first fixing portion 260 and the second fixing portion 262. During rotation of the swinging member 22, a portion of the swinging member 22 that is closer to the rotational axis 20 a may rotate along a circle for a shorter distance. Therefore, the movable portion 264 of the flexible printed circuit board 26 may be arranged adjacent to the rotational axis 20 a. That is, the movable portion 264 may be arranged to surround the rotational axis 20 a, in such a way that the rotational distance of the movable portion 264 may be reduced, and a length of the flexible printed circuit board 26 pulled by the swinging member 22 during the rotation of the swinging member 22 may also be reduced, such that the flexible printed circuit board 26 may be prevented to be torn apart.

As the first fixing portion 260 of the flexible printed circuit board 26 may rotate into and out of the receiving cavity 50 along the rotation of the swinging member 22, sealing foams may be provided on an outer surface of the flexible printed circuit board 26 to protect the flexible printed circuit board 26 from water and dust.

The rotation shaft 70 may be provided on the connection portion 224 of the swinging member 22. The camera module 240, the front flash 242, and the receiver 246 may all be arranged between the first end portion 220 and the rotation shaft 70. It should be understood that while the first end portion 220 of the swinging member 22 is rotating to the outside of the receiving cavity 50, the second end portion 222 may rotate along with the first end portion 220 in a direction away from the opening 14 a of the body 10. That is, during the rotation of the second end portion 222, the second end portion 222 may gradually move away from the third side frame 144 of the middle frame 14, such that a gap may be defined between the third side frame 144 and the second end portion 222. According to an embodiment shown in FIG. 16 and FIG. 17, a distance between the rotation shaft 70 and the first end portion 220 may be greater than that between the rotation shaft 70 and the second end portion 222. Therefore, when the first end portion 220 rotates to the outside of the receiving cavity, with a same angular velocity, the first end portion 220 may rotate for a longer distance in a circle, and the second end portion 222 may rotate for a shorter distance in a circle, such that the gap between the second end portion 222 and the third side frame 144 may be reduced.

In some other embodiments, as shown in FIG. 19, the rotation shaft 70 may be arranged at the second end portion 222 and at a position of the swinging member 22 close to the middle frame 14. Under such circumstance, the second end portion 222 may be disposed even closer to the rotation shaft 70, and the rotation shaft 70 may be disposed close to the third side frame 144 of the middle frame 14. Therefore, when the swinging member 22 is rotating, the rotation distance of the second end portion 222 in the circle may further be reduced, which may further reduce the gap between the second end portion 222 and the third side frame 144.

The above mentioned embodiments may provide the sliding mechanism formed by the sliding grooves engaging with the sliding blocks. However, in other embodiments, the sliding mechanism may include a sliding rail (such as protruded tracks) and a sliding element in other forms.

In some embodiments, as shown in FIG. 1, two sliding mechanisms may be provided. However, in some other embodiments, there may be one sliding mechanism. As shown in FIG. 20, the sliding groove 100 may be defined in the rear cover 12, and the sliding block 200 may be arranged on the swinging member 22.

According to the embodiments of the present disclosure, by providing sliding blocks 200 and 201 on the swinging member 22 and defining the sliding grooves 100 and 101 in the rear cover 12, and allowing the sliding blocks 200 and 201 to slide along the sliding grooves 100 and 101, the sliding blocks 200 and 201 may be guided in a direction, such that the swinging member 22 may be guided to rotate in a direction. The engagement between the rotation shaft 70 and the sliding mechanism may allow the swinging member 22 to rotate steadily. In other embodiments, three or more sliding mechanisms may be provided.

It may be understood that, in some other embodiments, the swinging member 22 may be connected to the rear cover 12 but without the rotation shaft 70. Instead, the swinging member 22 may be connected to the rear cover 12 via at least two sliding mechanisms. According to an embodiment shown in FIG. 21, the swinging member 22 may be connected to the rear cover 12 via two sliding mechanisms. To be specific, the two sliding grooves 100 may both be defined in the rear cover 12, and the two sliding blocks 200 may both be arranged on the swinging member 22. The sliding blocks 200 may be arranged in and slide along the corresponding sliding grooves 100, such that the swinging member 22 may shift upwards and leftwards during rotation. In this way, a gap may not be defined between the second end portion 222 and the third side frame 144.

In some other embodiments, the swinging member 22 may also define a plurality of sliding grooves, and a plurality of sliding blocks may be arranged on the rear cover 12. Alternatively, some of the sliding grooves may be defined in the rear cover 12, and the sliding blocks engaged with the sliding grooves may be arranged on the swinging member 22; while other sliding grooves may be defined in the swinging member 22, and the sliding blocks engaged with the other sliding grooves may be arranged on the rear cover 12. The arrangement may not be limited by the present disclosure.

It may be understood that the sliding mechanism may not be only for a purpose of guiding, but also for position limit. When the functional assembly 20 rotates to the first position inside the receiving cavity 50, the sliding block 200 may abut against a side wall at an end of the sliding groove 100 that is away from the opening 14 a, such that the functional assembly 20 may be prevented from rotating to a position further inside the mobile terminal. When the functional assembly 20 rotates from the first position to the second position outside the receiving cavity 50, the sliding block 200 may abut against a side wall at an end of the sliding groove 100 that is close to the opening 14 a, such that the functional assembly 20 may be prevented from rotating to a position further out of the receiving cavity 50.

Of course, in some other embodiments, the swinging member 22 may be rotatably connected to the rear cover 12 through the rotation shaft 70, and a sliding mechanism may not be needed (as shown in FIG. 16 and FIG. 17).

As shown in FIG. 22, as described above, in some embodiments, the functional assembly 20 may rotate between the first position, the second position, and the third position. To be specific, the functional assembly 20 may rotate in a first direction from the first position to the second position, and may rotate in a second direction from the first position to the third position. The first direction may be an anti-clockwise direction, and the second direction may be a clockwise direction.

As shown in FIGS. 22 to 30, the rotational axis about which the functional assembly 20 rotates in the first direction may be the same as that about which the functional assembly 20 rotates in the second direction.

To be an example, as shown in FIG. 22, the connection portion 224 of the swinging member 22 may be rotatably connected to the rear cover 12 through the rotation shaft 70. In some embodiments, the rotation shaft 70 may be fixed with the rear cover 12. When the functional assembly 20 rotates in the first direction and the second direction, the rotational axes 20 a on both occasions may be an axle center of the rotation shaft 70. In some embodiments, the camera module 240 and the front flash 242 may be arranged on a same side of the rotation shaft 70, and the receiver 246 may be arranged on an opposite side of the rotation shaft 70. When the swinging member 22 rotates in the first direction from the first position to the second position, the first end position 220 of the swinging member 22 may rotate to the outside of the receiving cavity 50, and the second end portion 222 may be located inside the receiving cavity 50. In this way, the camera module 240 and the front flash 242 may be exposed to the outside of the receiving cavity 50, and the receiver 246 may be positioned inside the receiving cavity 50. When the swinging member 22 rotates in the second direction from the first position to the third position, the second end portion 222 may rotate to the outside of the receiving cavity 50, and the first end portion 220 may be located inside the receiving cavity 50. In this way, the receiver 246 may be exposed to the outside of the receiving cavity 50, and the camera module 240 and the front flash 242 may be positioned inside the receiving cavity 50. According to some embodiments, the functional assembly 20 may rotate to protrude out of the receiving cavity 50 from two directions. Therefore, different functional components may be arranged on the two end portions of the swinging member 22. As the functional components are arranged at the end portions, when two functional components both need to be used, the swinging member 22 may rotate by a small angle to allow an easy operation.

In some embodiments, the sliding mechanism may be provided between the swinging member and the body. In some embodiments, as shown in FIG. 23, in case that the rotation shaft 70 is provided, two sliding mechanisms may also be provided at the same time. A first sliding groove 102 and a second sliding groove 103 of the two sliding mechanisms may both be defined in the rear cover 12. Each of the first sliding groove 102 and the second sliding groove 103 may be in shape of an arc. A center of the arc in which the first sliding groove 102 is located and a center of the arc in which the second sliding groove 103 is located may both lie on the axle center of the rotation shaft 70, and the first sliding groove 102 and the second sliding groove 103 may be arranged on two sides of the rotation shaft 70. The swinging member 22 may be provided with a first sliding block 202 and a second sliding block 203. The first sliding block 202 may be arranged within the first sliding groove 102 and slide along the sliding groove 102, and the second sliding block 203 may be arranged within the second sliding groove 103 and slide along the sliding groove 103.

As shown in FIG. 24, in some other embodiments, the swinging member 22 may be rotatably connected to the rear cover 12 through only two sliding mechanisms without the fixed rotation shaft. The center of the arc in which the first sliding groove 102 is located and the center in which the arc of the second sliding groove 103 is located may both lie on the rotational axis 20 a of the swinging member 22, and the first sliding groove 102 and the second sliding groove 103 may be defined at two opposite sides of the rotational axis 20 a.

The sliding mechanism may not only have a guiding function, but also have a function of position limit. To be specific, when the swinging member 22 rotates to the first position inside the receiving cavity 50, the first sliding block 202 may be positioned in a middle of the first sliding groove 102, and the second sliding block 203 may be positioned in a middle of the second sliding groove 103. When the swinging member 22 rotates in the first direction starting from the first position, the first sliding block 202 in the first sliding groove 102 may slide towards the opening 14 a along the first sliding groove 102, and the second sliding block 203 in the second sliding groove 103 may slide away from the opening 14 a along the second sliding groove 103. When the swinging member 22 reaches the second position, the first sliding block 202 may abut against the wall at an end of the first sliding groove 102 that is close to the opening 14 a, and the second sliding block 203 may abut against the wall at an end of the second sliding groove 103 that is away from the opening 14 a, such that the swinging member 22 may be prevented from rotating. Similarly, when the swinging member 22 rotates in the second direction starting from the first position, the first sliding block 202 in the first sliding groove 102 may slide away from the opening 14 a along the first sliding groove 102, and the second sliding block 203 in the second sliding groove 103 may slide towards the opening 14 a along the second sliding groove 103. When the swinging member reaches the third position, the first sliding block 202 may abut against the wall at an end of the first sliding groove 102 that is away from the opening 14 a, and the second sliding block 203 may abut against the wall at an end of the second sliding groove 103 that is close to the opening 14 a, such that the swinging member 22 may be prevented from rotating.

According to the above mentioned embodiments, when the functional assembly rotates in the first direction and the second direction to protrude out of the receiving cavity, the functional assembly may protrude from the same side frame of the middle frame 14. Under such circumstance, a position of the opening 14 a of the middle frame 14 may be defined is shown as FIGS. 4 to 6.

In some other embodiments, when the swinging member 22 is arranged at the second position or the third position, the first end portion 220 may rotate to out of the receiving cavity 50, and the second end portion 222 may be disposed inside the receiving cavity 50.

To be an example, as shown in FIG. 25, the second end portion 222 of the swinging member 22 may be rotatably connected to the rotation shaft 70. In some embodiments, the first side frame 140 and the third side frame 144, which are arranged adjacent to each other, may be disconnected to define an opening, as shown in FIG. 7. Under such circumstance, when the swinging member 22 rotates from the first position to the second position, the first end portion 220 may protrude to the outside from the first side frame 140. When the swinging member 22 rotates from the first position to the third position, the first end position 220 may protrude to the outside from the third side frame 144, which is adjacent to the first side frame 140. In some other embodiments, the swinging member 22 may be circular sector in shape, as shown in FIG. 26 and FIG. 27. When the swinging member 22 rotates from the first position to the second position, a side of the first end portion 220 may rotate to protrude from the first side frame 140 to be exposed out of the body 10, and an opposite side may remain inside the body 10. When the swinging member 22 rotates to reach the third position, a side of the first end portion 220 may remain inside the body 10, and an opposite side may rotate to protrude from the third side frame 144, which is adjacent to the first side frame 140, to be exposed out of the body 10.

In some other embodiments, as shown in FIG. 9, the first side frame 140 may define an opening 14 f, and the second side frame 142 opposite to the first side frame 140 may also define an opening 14 f. Under such circumstance, when the swinging member 22 rotates from the first position to the second position, the first end portion 220 may rotate to protrude from the first side frame 140 of the middle frame 14. When the swinging member 22 rotates from the first position to the third position, the first end portion 220 may protrude from the second side frame 142, as shown in FIG. 28. In other embodiments, the swinging member 22 may be circular sector in shape, when the swinging member 22 is at the second position, a side of the first end portion 220 may protrude from the first side frame 140; and when the swinging member 22 is at the third position, an opposite side of the first end portion 220 may protrude from the second side frame 142, as shown in FIG. 29 and FIG. 30.

As shown in FIGS. 31 to 35, in some other embodiments, the rotational axis about which the functional assembly 20 rotates in the first direction may be different from that about which the functional assembly 20 rotates in the second direction.

For example, as shown in FIG. 31, a first rotation shaft 71 and a second rotation shaft 72 may be fixed on the body 10, and the swinging member 22 may be rotatably connected to the rear cover 12 through the first rotation shaft 71 and the second rotation shaft 72. To be specific, when rotating in the first direction, the swinging member 22 may rotate around the second rotation shaft 71, the rotational axis 20 a of the swinging member 22 may be an axle center of the second rotation shaft 72. When rotating in the second direction, the swinging member 22 may rotate around the first rotation shaft 71, on this occasion, a rotational axis 20 b of the swinging member 22 may be an axle center of the first rotation shaft 71.

To be specific, each of the first end portion 220 and the second end portion 222 of the swinging member 22 may define a major arc shaped engaging recess 221, and the major arc shaped engaging recess 221 may have a recess opening 223. The first rotation shaft 71 and the second rotation shaft 72 could be engaged into the engaging recess 221, or detached from the engaging recess 221 through the recess opening 223. The first end portion 220 of the swinging member 22 may be engaged with the first rotation shaft 71 through the major arc shaped engaging recess 221 defined on the first end portion 220, and the second end portion 222 may be engaged with the second rotation shaft 72 through the major arc shaped engaging recess 221 defined on the second end portion 222.

A radius of the major arced engaging recess 221 may be slightly greater than or equal to a radius of the first rotation shaft 71 and a radius of the second rotation shaft 72, such that the first rotation shaft 71 and the second rotation shaft 72 may be engaged into the major arced engaging recess 221 to allow the swinging member 22 to rotate around the first rotation shaft 71 or the second rotation shaft 72. A width of the recess opening 223 of the engaging recess 221 may be smaller than the radius of the first rotation shaft 71 and the radius of the second rotation shaft 72, such that the first rotation shaft 71 and the second rotation shaft 72 may remain as being engaged inside the engaging recess 221 when no external force is applied. In some embodiments, some portions on two sides of the recess opening 223 of the major arced engaging recess 221 of the swinging member 22 may be made of an elastic material, such that the two sides of the recess opening 223 of the major arced engaging recess 221 may be deformed elastically to allow the first rotation shaft 71 and the second rotation shaft 72 to be engaged into the major arced engaging recess 221 through the recess opening 223 or to be detached from the major arced engaging recess 221 through the recess opening 223.

When the driving mechanism 30 applies a force to the first end portion 220 of the swinging member 22, and a direction of the force is opposite to a facing direction of the recess opening 223 of the major arced engaging recess 221 of the first end portion 220, the first end portion 220 of the swinging member 22 may be detached from the first rotation shaft 71, and the second end portion 222 may remain as rotatable connecting with the second rotation shaft 72. Therefore, the swinging member 22 could rotate around the second rotation shaft 72, and the first end portion 220 could rotate to protrude out of the receiving cavity 50, while the second end portion 222 may stay inside the receiving cavity 50.

When the driving mechanism 30 applies a force to the second end portion 222 of the swinging member 22, and a direction of the force is opposite to a facing direction of the recess opening 223 of the major arced engaging recess 221 of the second end portion 222, the second end portion 222 of the swinging member 22 may be detached from the second rotation shaft 72, and the first end portion 71 may remain as rotatable connecting with the first rotation shaft 71. Therefore, the swinging member 22 could rotate around the first rotation shaft 71, and the second end portion 222 could rotate to protrude out of the receiving cavity 50, while the first end portion 220 may stay inside the receiving cavity 50.

In some embodiments, a sliding mechanism may be provided between the swinging member 22 and the rear cover 12, such that a rotation of the swinging member 22 along an arc trajectory could be achieved through the engagement between the swinging member 22 and the first rotation shaft 71 and the engagement between the swinging member 22 and the second rotation shaft 72. The sliding mechanism may include a first sliding groove 104 and a second sliding groove 105 defined on the rear cover 12, and a sliding block arranged on the swinging member 22. Both the first sliding groove 104 and the second sliding groove 105 may have an arc shape.

As shown in FIG. 32 and FIG. 33, a center of an arc in which the first sliding groove 104 is located may lie on an axle center of the first rotation shaft 71, and a center of the arc in which the second sliding groove 105 is located may lie on an axle center of the second rotation shaft 72. An end of the first sliding groove 104 away from the opening 14 a of the middle frame 14 and an end of the second sliding groove 105 away from the opening 14 a of the middle frame 14 may communicate with each other.

When the swinging member 22 rotates in the first direction to protrude out of the receiving cavity 50 from the first position, the sliding block 204 may slide along the second sliding groove 105. When the swinging member 22 rotates to the second position, the sliding block 204 may abut against a wall of an end of the second sliding groove 105 close to the opening 14 a of the middle frame 14 to prevent the swinging member 22 from continuing rotating.

When the swinging member 22 rotates in the second direction to protrude out of the receiving cavity 50 from the first position, the sliding block 204 may slide along the first sliding groove 104. When the swinging member 22 rotates to the third position, the sliding block 204 may abut against a wall of an end of the first sliding groove 104 close to the opening 14 a of the middle frame 14 to prevent the swinging member 22 from continuing rotating.

When the swinging member 22 rotates from the outside of the receiving cavity 50 to the first position inside the receiving cavity 50, the sliding block 204 may be positioned at an end of the first sliding groove 104 communicated with the second sliding groove 105, and the sliding block 204 may abut against a wall of the end of the first sliding groove 104 communicated with the second sliding groove 105, such that the swinging member 22 may be prevented from continuing rotating.

Both of the first sliding block 205 and the second sliding block 206 may be provided on the swinging member 22.

A center of an arc in which the first sliding groove 106 is located and a center of an arc in which the second sliding groove 107 is located may lie on a rotational axis 20 c of the swinging member 22 when the swinging member 22 rotates in the first direction. A center of an arc in which the third sliding groove 108 is located and a center of an arc in which the fourth sliding groove 109 is located may lie on a rotational axis 20 d of the swinging member 22 when the swinging member 22 rotates in the second direction.

An end of the first sliding groove 106 away from the opening 14 a of the middle frame 14 may communicate with an end of the third sliding groove 108 away from the opening 14 a of the middle frame 14, and an end of the first sliding groove 106 close to the opening 14 a of the middle frame 14 may be spaced from an end of the third sliding groove 108 close to the opening 14 a of the middle frame 14. An end of the second sliding groove 107 away from the opening 14 a may communicate with an end of the fourth sliding groove 109 away from the opening 14 a, and an end of the second sliding groove 107 close to the opening 14 a may be spaced from an end of the fourth sliding groove 109 close to the opening 14 a of the middle frame 14.

When the swinging member 22 rotates from the outside of the receiving cavity 50 to the first position inside the receiving cavity 50, the first sliding block 205 may abut against a wall of the end of the first sliding groove 106 communicated with the third sliding groove 108, and the second sliding block 206 may abut against a wall of the end of the second sliding groove 107 communicated with the fourth sliding groove 109, such that the swinging member 22 may be prevented from rotating.

As shown in FIG. 36 and FIG. 37, in some embodiments, a plurality of the functional assemblies 20 may be provided, and each of the plurality of functional assemblies 20 may include at least one functional component. For example, in FIG. 36, functional components 24 arranged on a swinging member 22 a may include a camera module 240 and a front flash 242. A functional component 24 arranged on another swinging member 22 b may include a receiver 246. In some embodiments, rotational axis 20 a of each functional assembly 20 may be overlapped. When one of the functional components needs to be used, the driving mechanism 30 may drive the swinging member 22, which is provided with the corresponded functional component, to rotate to protrude out of the receiving cavity 50. For example, when the camera module 240 is needed, the driving mechanism 30 may drive the swinging member 22 a, which is provided with the camera module 240, to rotate to the outside of the receiving cavity 50, such that the camera module 240 may rotate to protrude out of the receiving cavity 50.

An output end of the gear box 322 may be connected with the screw 340 to drive the screw 340 to rotate. An end of the connection element 344 may define a screw hole and a through hole. The screw 340 may be threaded into the screw hole to achieve a thread connection between the connection element 344 and the screw 340, such that rotation of the screw 340 may drive the connection element 344 to move along the screw 340. The guide rod 342 may be inserted into the through hole to guide a moving direction of the connection element 344. Another end of the connection element 344 may be connected with an end of the pushrod assembly 36.

Another end of the pushrod assembly 36 may extend through the through hole 147 defined on the partition board 145 and the seal ring 60 inside the through hole 147, such that the pushrod assembly 36 may protrude from the second receiving space 54 to the first receiving space 52 to be connected to the functional assembly 20. To be specific, the pushrod 36 may include a pushrod 360, a spring 362 provided to surround a periphery of the pushrod 360, and a sleeve 364 to encase the pushrod 360 and the spring 362.

The sleeve 364 may be provided with a guide track 366, and the swinging member 22 may be provided with a guide block 228, which may be placed inside the guide track 366. When the swinging member 22 rotates, the guide block 228 may slide inside and along the guide track 366. The sleeve 364 may abut against the guide block 228 to support the swinging member 22, so as to drive the swinging member 22 to rotate.

In other embodiments, there may be a plurality of the pushrod assemblies 36 and a plurality of the transmission assemblies 34. The plurality of the pushrod assemblies 36 may be arranged with distance apart from each other, and the plurality of the transmission assemblies 34 may be arranged with distance apart from each other. As shown in FIG. 40, two pushrod assemblies 36 may be arranged at two sides of the power assembly 32 respectively, and two transmission assemblies 34 may be arranged at two sides of the power assembly 32 respectively.

An end of the gear rack 36 a may engage with the gear 34 a, and another end of the gear rack 36 a may be connected to the swinging member 22. The motor 32 a may drive the gear 34 a to rotate to further drive the gear rack 36 a to reciprocate along the predefined direction, the reciprocating of the gear rack 36 a may drive the swinging member 22 to rotate.

In some other embodiments, as shown in FIG. 43 and FIG. 44, the driving mechanism may include a first magnet 31 and a second magnet 33, which are arranged on the body 10 with distance apart from each other, and a third magnet 35 and a fourth magnet 37, which are arranged on the swinging member 22 with distance apart from each other. The third magnet 35 may be arranged with respected to the first magnet 31, and the fourth magnet 37 may be arranged with respected to the second magnet 33. On this occasion, the swinging member 22 may be connected to the body 10 without a fixed rotation shaft.

When the first magnet 31 repels the third magnet 35, and the second magnet 33 attracts the fourth magnet 37, the swinging member 22 may rotate in the first direction, and a rotational axis 20 e may be positioned at a connection between the second magnet 33 and the fourth magnet 37.

When the first magnet 31 attracts the third magnet 35, and the second magnet 33 repels the fourth magnet 37, the swinging member 22 may rotate in the second direction, and a rotational axis 20 f may be positioned at a connection between the first magnet 31 and the third magnet 35.

The first magnet 31 and the second magnet 33 may both be electromagnets, magnetic poles of the first magnet 31 and those of the second magnet 33 may be reversed by changing the electric current. Of course, the third magnet 35 and the fourth magnet 37 may also be electromagnets. Alternatively, the first, the second, the third, and the fourth magnets 31, 33, 35, and 37 may all be permanent magnets, on this occasion, directions of the magnetic poles may be changed by rotating the magnets.

It may be understood that, in some other embodiments, the third magnet 35 and the fourth magnet 37 may maintain in a state of mutual attraction, such that the swinging member 22 may rotate in one direction only.

In addition to automatically controlling the rotation of the swinging member 22, manual controlling may also be available.

For example, FIG. 45 illustrates a driving mechanism including an elastic element 31 c, which may be elastically abut against the body 10 and the swinging member 22, a guide rack 33 c provided on the swinging member 22 along a predefined direction, and a positioning mechanism 35 c. The positioning mechanism 35 c may include a rotation element 350, a pressing element 352, a positioning block 354, and a second elastic element 356. The rotation element 350 may be rotatably connected to the body 10. The pressing element 352 may be rotatably connected to an end of the rotation element 350. The positioning block 354 may be rotatably connected to another end of the rotation element 350 away from the pressing element 352. The second elastic element 356 may be connected to the positioning block 354 to rest the positioning block 354.

The positioning block 354 may be arranged to limit the position of the guide rack 33 c. An end of the pressing element 352 away from the rotation element 350 may extend to the outside of the body 10. When the end of the pressing element 352, which extends to the outside of the body 10, is pressed, the rotation element 350 may be driven to rotate, and the rotation element 350 may drive the positioning block 354 to be released from positioning the guide rack 33 c.

When the swinging member 22 is at the first position, the first elastic element 31 c may be pressed to deform, and the positioning mechanism 35 c may limit the guide rack 33 c to a first predefined position, such that the first elastic element 31 c may remain as being pressed and deformed. When the swinging member 22 needs to rotate to protrude, the pressing element 352 may be pressed to drive the rotation element 350 to rotate, such that the rotation element 350 may drive the positioning block 354 to be released from limiting the guide rack 33 c, the first elastic element 31 c may be restored to extend to drive the swinging member 22 to protrude out of the body 10. At the same time, the guide rack 33 c may slide to the outside of the body 10. When the guide rack 33 c slides to a second predefined position, the swinging member 22 may reach the second position, and the positioning block 354 may limit the guide rack 33 c to prevent the guide rack 33 c from sliding, such that the first elastic element 31 c may be ceased to extend outwards, and the swinging member 22 may be prevented from rotating. When the swinging member 22 needs to rotate to the first position, the swinging member 22 may be pressed to rotate to the inside of the body 10, at this point, the first elastic element 31 c may be extruded. Also, the guide rack 33 c may slide to the inside of the body 10. When the guide rack 33 c slides to reach the first predefined position, the positioning block 354 may limit the position of the guide rack 33 c, such that the guide rack 33 c may be prevented from sliding, and the swinging member 22 may be limited to the first position.

It may be understood that the driving mechanism may be provided to be other mechanisms, which may not be limited herein.
